通过水热反应合成了一个具有二维层状结构的配位聚合物[Ni(bbim-4)(L1)]n(bbim-4=1,4-双(咪唑-1-基)丁烷,L1=对苯二乙酸阴离子),经元素分析、红外光谱、粉末和单晶XRD对产物进行了表征.晶体属于单斜晶系,空间群为P21/n,主要晶胞参数:a=9.772 8(3),b=8.634 0(3),c=11.154 0(3),β=92.755(2),Z=2,V=940.07(5)3,Dc=1.558 mg.mm-3,μ(CuKα)=1.804 mm-1,F(000)=460.此配位聚合物具有二维聚合物层,层与层之间通过范德华力形成一个三维的超分子结构.由热重分析研究了配位聚合物的热稳定性.
A coordination polymer [Ni (bbim-4) (L1)] n (bbim-4 = 1,4-bis (imidazol-1-yl) butane with a two-dimensional layered structure was synthesized by hydrothermal reaction, L1 = p-phenylene diacetate anion), the product was characterized by elemental analysis, IR, powder and single crystal XRD.The crystals belong to the monoclinic system with the space group of P21 / n and the main unit cell parameters: a = 9.772 8 (3) b = 8.634 0 3 c = 11.154 0 3 β = 92.755 2 Z = 2 V = 940.07 53 Dc = 1.558 mg.mm- 3, μ (CuKα) = 1.804 mm-1, F (000) = 460. The coordination polymer has a two-dimensional polymer layer with a three-dimensional supramolecular structure formed by van der Waals forces, The thermal stability of coordination polymers was analyzed.
